The compact performance segment within the automotive specialty equipment market may be all about accessories and products for smaller-sized cars and vehicles, but the segment itself burst its "compact" seams in 2002, according to SEMA, the Specialty Equipment Market Association. At its sixth International Auto Salon last weekend, SEMA announced that 2002 retail sales of accessories and other products for compact vehicles were $US2.367 billion in the United States, an astounding growth rate of 55.9%. SEMA has tracked sales in this new niche of products for cars and trucks since 1997.  Just six years ago, sales stood at $295 million.
